The stone mines of Melissa, 2.5 square miles of stone, are an extraordinary place, but out of every tourist route. Difficult to reach and to visitors (visits are planned, but only by appointment), the "Pirriera" has thirty meters high ceilings, stone columns large five, exudes the history of the work of the men who worked there. The stones of these quarries were used for the construction of many buildings and decorations related to the Sicilian Baroque.
